Hello! I've got a problem with port a 2.4.26 kernel version on a embedded i386ex development board. Previously I worked on a 2.2 kernel with simple tweaks (especially eXecute In Place support). Next I've tried to do it with the last 2.4 kernel. The host have only 3M of memory but it works with with 2.2.
Could onyone help me with memory address setup?
I inlude the last log :
